Patent DE-2824167-A1 (DE)
Inventor: SCHWARZWAELDER JOERG
IPC: B61L3/22
Filed: 1978-06-02
Abstract: In order, at the start of a route area, to reduce the risk of operational impediments resulting from faults in the signal reception, the reception level is to be increased in this area. For this purpose, the track conductor (LS) is laid at the end of the loop in such a way that two additional loops (ZS 3, ZS 4) are produced, which loops (ZS 3, ZS 4) approximately double the magnetic field, available for the reception aerial on a vehicle, at the end of the loop, i.e. at the start of the area. <IMAGE>
Patent DE-2833531-A1 (DE)
Inventor: SANTIAGO ANDRES
IPC: E04D13/12
Filed: 1978-07-31
Abstract: The safety roof hook (1) for the suspension of ladders has a rod-shaped central part (2). At one end, it has a lug (3) which is bent off approximately at right angles. A suspension bow (6), which is approximately in the form of an arc of a circle and is bent off in the opposite direction to the lug, is fitted at the other end of the safety roof hook. In order to permit the safe suspension of spring closures of safety cables, the invention proposes that the suspension bow (6) have, at a distance from its free end, a bent portion (4) which projects outwards with respect to the circle arc. <IMAGE>

Abstract: The robot includes a jib arm with adjustable length, and which can be swivelled on two mutually perpendicular axes. On the free end of the jib is a holder for the welding gun, and the holder can be moved in >=2 mutually perpendicular planes. Decoders monitor all the movements of the robot, and feed signals to an electronic comparator fed with pre-programmed values so any deviation can be eliminated. At least the two angular positions of the jib are transmitted to two decoders via pairs of gears or gear segments; and >=1 gear in each pair is pulled against the other gear in the pair by a tension spring. Involute gears are pref. used; and the decoders are pref. fitted on the swivelled gear in each pair of gears.

Title: Solubilisation of basic ferric sulphate - from oxidn. of hydrated ferrous sulphate, by reaction with sulphuric acid giving prod. useful as sewage flocculant
Inventor: CHERDRON EGON DIPL CHEM DR
IPC: C01G49/14
Filed: 1978-08-05
Abstract: Increasing the water-solubility of basic ferric sulphate (I) obtd. by oxidn. of solid ferrous sulphate (II) contg. water of crystallisation is effected by mixing the scarcely water-soluble (I) with dil. (20-40%) H2SO4 in the molar ratio 2 Fe(OH)SO4:0.3-0.7 H2SO4 and with recycled soluble (I) at a temp. between 15 and 80 degrees C and then allowing to solidify by storage. The solubilised (I), which is hydrated and has a molar ratio of 1 Fe2O3: 2.3-2.7 SO3 and gives under 2 (under 1) wt.% insol. residue, is useful as a flocculant for sewage. The process is esp. economical if waste H2SO4 esp. contg. Fe (from TiO2 mfr.) is employed.

Title: Extn. of tobacco flavouring volatiles - by heating tobacco in stream of inert gas and condensing
Inventor: OSBORNE JUN J SCOTT
IPC: A24B15/24
Filed: 1978-10-24
Abstract: Tobacco is contacted with a stream of non-reactive gas and heated to volatilise the flavourants, which are then condensed from the gas stream. The improvement is that the tobacco is heated to 140-180 degrees C, for sufficient time to achieve a wt. loss from the tobacco of 3-10% in excess of the loss represented by oven volatiles. The fraction of volatiles obtained has the flavour and aroma of tobacco, and is storable. It is used to augment the flavour of low flavour smoking materials, esp. the low tar type. When high flavour tobaccos are used, e.g. Oriental, the residue is still suitable for smoking.
Patent DE-2852791-A1 (DE)
Title: Transmission characteristics analysis for data or telephone lines - obtaining harmonic amplitudes via Fourier analysis to ascertain noise interference factor
Inventor: BAUERNFEIND KARL DIPL ING
IPC: G01R27/28
Filed: 1978-12-06
Abstract: The analysing system with a Fourier processor uses test pulses which comprise a series of differing frequency oscillations with amplitude and phase corresp. to a tangential summation function. At the transmission side the test pulse has only one or a limited number of harmonics, while the amplitude values for a larger number of harmonics are obtained rather Fourier analysis of the received pulse from the object. These amplitude values are used to provide the noise interference factor for the line. The system can be used for a telephone or data line, or for determining the quantisation distortion for a PCM system.

Title: Operation of internal combustion engines with thermal cracking gas - from partial oxidn. of liq. fuels
Inventor: LINDENMAIER KLAUS DIPL PHYS DR
IPC: F02M27/00
Filed: 1979-02-06
Abstract: Internal combustion engines are run on gas from thermal cracking of liquid hydrocarbons at 1000-1300 degrees C, mixed with 25-30% of the air required for complete combustion, the temp. being controlled by recycling part of the cracking gas after cooling. No catalyst is required, so that normal leaded petrol may be used. Purely thermal cracking is obtd. without formation of C, and the energy content of the cracked gas is not reduced by dilution with steam or exhaust gases. Operation by gas reduces pollution and improves cold starting.

Title: Disintegrating machine for wood - has feed conveyor working together with counter-rotating deflector roller
Inventor: HERMEIER WILHELM DIPL ING
IPC: B27L11/00
Filed: 1979-03-28
Abstract: The disintegrator handles wood material and uses a shredding tool (10) fitted with a number of blades (9). The material (12) is advanced towards the rotating tool by a conveyor (1) fitted with lugs (17) on which the wood material rests. Before the material reaches the shredding tool (10) it passes underneath the roller (3) which is height-adjustable along an arc path (4). The gap between the roller (3) and the top surface of the conveyor (1) determines the height of material layer to be handled by the shredding tool. In order to control this height and to prevent overloading of the shredding tool a deflecting roller (14) is provided whose rotation is opposed to the conveyor motion. The roller (14) repels any piece of material coming towards the tool (10) at a layer height in excess of the gap (A) and prevents it from reaching the roller (3).

Title: Automatic balance with measurement time adjustment - has circuit for summing digitised force compensation current and comparing with trend limits
Inventor: KNOTHE ERICH
IPC: G01G23/37
Filed: 1979-06-15
Abstract: An electrical balance with automatic measurement time adjustment has a fore compensation electromagnetic system balancing the load. The compensation current is digitised and summed to produce a load signal. It is a high resolution balance with simple optimal measurement time adaption to the weighing process in hand. The digital partial measurement results are multiplied by a constant, the product of the last complete result subtracted, and the differences summed and stored in a trend register whose contents are continuously compared with a defined trend limit. After each result the summation of partials is concluded or continued up to a given number of partials. A rest condition signal is placed on the indicator input when the trend register contents are below the smallest defined trend limit.

Filed: 1980-07-21
Abstract: A method of influencing biological systems, substances, terrestrial areas, electronic devices and the like, and/or influencing their processes such as mass exchange, reactions and reaction prods., consists of utilising electromagnetic, particle and/or photon rays and/or currents, magnetic direct and/or alternating fields, etc. and varying the quality of these influencing radiations of fields. Procedures for varying the quality include frequency and amplitude modulation procedures and polarisation. Used for modifying, accelerating, promoting etc. the effects produced naturally by radiation, emissions, magnetic and similar fields. Whereas so far only the intensity of such influences has been varied, the new method consists also in varying the quality. In this way damage resulting from excessive intensity, as in the previous methodsof improving or attempting to improve influences, can be avoided.
